CYLINDER-LUBRICATOR.

SPECIFICATION forming part of Letters Patent NO. 345,929, dated July 20, 1886.

Application filed April 15, 1885.

To all whom it may concern:

Be it known that I, CHARLES \V. SHER- BURNE, of Boston, in the county of Suffolk and State of Massachusetts, a citizen of the United States, have invented a new and useful Improvement in Oylinder-Lubricators, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, i'orminga part ofthis specification in explaining its nature.

This invention relates to thatclass of lubrieator which employs a hydrostatic column and a drop-up sight-feed, and is specially de signed for use on locomotives, and especially of those locomotives which have an air or vacu um brake attached. It is provided with three sight-feed glasses.

The principal feature of novelty in this apparatus is in making the passages, which are usually made by exterior piping within the metal of the shell of the lubricator, and in so arranging them in connection with each other and with the outside piping as to reduce the exterior piping to a minimum, and also to provide a more convenient filling apparatus than is at present in use.

In the drawings, Figure 1 is a vertical longitudinal section. Fig. 2 is another vertical longitudinal section transverse to Fig. 1. Fig. 3 is a transverse section on the line was of Fig. 1. Figs. 4-, 5, and 6 are transverse sections of the two-way cock and its housing.

A two-way cock already forms a part of a patent application No. 153,147, filed February 17, 1885, on which this is an improvement.

In the drawings, A is the body of thelubricator.

B is the CO1l(l6llS6l',WlllCl1 receives the steam from the boiler or other proper source of steam-supply through the pipe I), which steam, by condensation, forms water, which is transmitted to the bottom of the oil-vessel through the pipe I). A branch, I)", of the same pipe,

which leadsto the condenser, also leads into the oil-delivery, and thus the same .steamprss ure is exerted upon the opposite ends of the 0il-column contained in the apparatus, because the same steam-pressure that rests upon the top of the waterin the condenser B is applied,

through the pipe b to resist the expulsion of oil from the apparatus, and hence the rate of expulsion will be determined solely by the gravity of the water in the condenser 13 and its attached pipe I) and the preponderance of this watercolumn in the reservoir A and in the delivery 'iipes.

C is a sight'feed glass having the usual nip pie, (1, entering its bottom for the delivery of oil, which delivery is controlled by means of the cock (1. This cock controls a pipe, which leads through the side of the reservoir A and turns upward to near the top of the reservoir, and receives from the top of the reservoir the oil that is flooded out by the water that descends from the condenser B and pipe I). Another pipe, E, which takes the oil, if necessary, from the samelevcl in the reservoir hat the pipe 0 takes it from, leads through the side, of the reservoir to the housing at the top of the sight-feed glass 0. The two my cock F, at the top of the sight-feed glass 0, deten mines by its position whether oil shall be taken through the sightfeed glass,it being necessary in order to keep the lubrication of a cylinder constant that such means should be provided when asight feed glass is broken, and such a provision for taking oil through a two-way cock, either through or over asight-feed chamber, is shown in the Seibert Patent No. 214,589, of April 22, 1879, although the details of the contrivance in that apparatus differ from the details of the two-way cock in this application. The contrivance, also, for putting the same pressure upon both ends of the oil-column, by means ofa branch steanrpipe, is shown in another Seibert Patent No. 179,226, of June 17, 1876, on the details of which this apparatus is an improvement.

G is the tillingcup, which isa permanentlyeovered vessel having perforations g in its cover, which cover also is formed as a basin. Through a gland in the center of the cover of the cup G is the stem gof a spindle-val\ 'e, which, when screwed down to its seat in the bottom of the cup G, serves to close the passage y into the reservoir A.

(t is the drainage-vent of the reservoir A. This has applied to it a pet-cock (not shown .in the drawings) by which it can be opened or closed at will, it being closed during the working of the lubricator, and opened only to drain it.

The described apparatus, consisting of the tunnel-shaped filling-cup G, with its valve and permanent cup-cover, perforated as described, is a great improvement on the former apparatus for filling the reservoir of the lubri cator. It avoids the difficulty of seating the plug on the lubricator, the chance of losing the removable filling plug generally employed, and is practically much more convenient than the arrangement hitherto employedin connection with replenishing the oil of the lubricator.

In Fig. 2 one of the sight-feed glasses, 0, is shown as broken, and the two-way cock F on that side is shown as so turned as to take the oil-feed from the top of the reservoir and OVGI the sightfeed glass 0, instead of through the sight-feed glass, as shown in thelett-hand side of Fig. 2. It will be noticed that the pipes ll of Fig. 2 open into the cavity of the reservoir at a slightly lower level than the pipe E in Fig. 1, and this is advisable where an air-brake and locoinotive-cylinder oiling apparatus are combined in the same cup, because it is a little more important to oil the main cylinder of a locomotive than it is to oil the air-brake, and if occasion comes for sacrificing either, the air-brake should be trusted without oiling rather than the main cylinder of the locomotive, especially as the oil cylinder of an airbrake would. be likely to do better withoutoil than the main cylinder of the locomotive. Still, I do not consider this detail as at all essential.

The two-way cock (shown in elevation in Figs. 7 and 8 on a larger scale than in the other drawings, and shown in transverse section in Figs. 4-, 5, and 6, and in vertical section in Figs. 1 and 2) differs somewhat from the twoway cock described in the application of February 17,1885. As it is desirable topnt steampressure upon the top of the sight-feed glass, as shown in Fig. 1, as well as upon the bottom throu h the water-induction )i 3e I) and also s l l to put steamprcssure upon the top of the oilreservoir,when the two-way cock is in the position shown on the right-hand side of Fig. 2, the construction of the cock is modified. A vertical hole, f, is made in the two-way cock F, which extends upward until it opens into the transverse passage f, which transverse passage is on the level of the steam-passage connected with the steam-pipe b and hence the current of steam passing through the steam-passage b will exert a steam-pressure on the top of the water in the sight-feed glass 0, and also will go forward with the oil through the steam and oil pipe I) or b of Fig. 3, into which this transverse passage f opens when the two-way cock F is in the position shown at Fig. 1.

Fig. 5 shows a transverse section of the twoway cock, F, on the line y y of Fig. 8. On the outside of the cock, on the level of this line and opposite each other, are grooves f which are terminated at one end by branches leading into the groovef, which is on the level of the line 2 z of Figs. 7 and S. This groovef eX- tends rather more than three-quarters around the barrel of the cock F, so that when the cock is set in the position shown on the right side of Fig. 2, which is illustrated in section in Fig. 5, on the level of the line y y of Figs. 7 and 4:, on the level of the line 2 z of Figs. 7 and 8, there will be a channel of oil threequarters around the cock on the level of the oil-passage e of Fig. 1, and this channel around the cock will communicate through the vertical branch passages shown in Figs. 7 and 8, with the groovef on the level of the line y y, and through this groove f with the oil and steam passages b b and with the steam-passage I)".

At and above and shortly below the level of the line as x of Fig. 2 the wall of the reservoir A is thickened on one side, as shown in Fig. 3, and has a pretty large boss of irregular form made in it. In this thickened wall and boss are made oil-passages Zr", which correspond in duty to the oil-passage b of Fig. 1; but steam does not reach them until they arrive at the metallic boss A. In this metallic boss are branch steam-pipes b, which communicate with the induction-steam pipe 6, as shown in Fig. 3, and feed steam to couplings N, which lead to the steam-cylinders. Through the hollow of these couplings steam-pressure is brought upon the top of the sight-feed glass or the top of the reservoir, as the case may be, through the oil-conduits If, and a current of steam accompanies the oil through the coup lings F.

It will be seen that the details of the twoway cock F differ slightly, according to their position, as shown in Fig. 3, but not in principle, according as the housing has passages on opposite sides of the cock as return-passages in its stem.

1 claim as my invention and desire to secure by Letters Patent of the United States- 1. The reservoir A, having its wall thickened near its top on one side and provided with the boss A at or near its top, said thickened wall and boss having oil-channels If and steam-channels b therein, substantially as and for the purposes described.

2. The two-way cock F, provided with two sets of exterior grooves, f 3 f, at different levels and of different lengths, which two sets of grooves communicate with each other, substantially as described.

3. The two-way cock F, having the interior vertical passage, f, and interior transverse passage, f, in combination with the exterior connecting passages, f f of diiferentlcngths, substantially as and for the purposes described.
